Abstract: A method for processing a carpet product including face yarns and a backing material embedding a lower portion of the face yarns, using an apparatus including a container for receiving at least a portion of the carpet product, the container including at least one rotary crank positioned in the container, with an upright wall having an unravelling arrangement positioned in the circumference of the rotary crank, the unravelling arrangement including protrusions on the upright wall extending into the container from the wall towards the rotary crank, the method including feeding the carpet product into the container, rotating the rotary crank to induce that the carpet product travels along the protrusions for unravelling the carpet product in a first fraction including at least part of the face yarns and a second fraction including at least part of the backing material.

Abstract: The invention provides a method for making fibers and yarns having improved dyeability with reactive and disperse dyes, resistance to staining and improved mechanical properties and characteristics. The method includes blending a polyolefin polymer and a fibril forming polymer to provide a mixture of polyolefin and fibril forming polymers. The mixture is conducted to a hot melt extruder to provide a substantially homogenous molten mixture of polyolefin and fibril forming polymers. The molten mixture is forced through a spinneret having a length to diameter (L/D) ratio ranging from about 3 to about 30 to provide a fiber having a polyolefin matrix and elongate, substantially discontinuous fibrils of the fibril forming polymer dispersed into the polyolefin matrix, whereby the exterior surface of the fibers is substantially devoid of fibrils. Fibers made by the process of the invention are useful as carpet face yarn, in textiles, upholstery and other industrial applications, like chemical industry and others.

Abstract: A process for the deposition of thick coatings with a thickness >1 mm on products made of copper or alloys thereof, wherein said products are subjected to the following operations: surface activation of the product made of copper or alloys thereof; optional heat stabilization to a temperature below the ones causing deterioration of the chemical and physical properties of the copper or alloys thereof; deposition of a first layer, for example of Ni or alloys thereof; optional interdiffusion heat treatment; optional activation of the surface of the first layer; thermal stabilization of said product at a temperature of between 20.degree. and 400.degree.
